Well, I honestly have no idea. I know for sure the sprinklers_pi program works with OSPi’s shift register. I have never tested it with direct GPIO outputs. The source code is all there, so perhaps you can add some debugging code to help find out what’s happening. By the way, make sure you are running the program with root permission — GPIO operations require root permission.
